We report here in detail the WDM performance of a wide‐angle novel X ‐junction switch (TSXB) that we developed earlier. At a full branching angle of 1.5°, our new design achieves a bandwidth of 145 nm (1470–1615 nm) at 1.5 dB over which the crosstalk is kept below −18.0 dB. Maintaining the same order of bandwidth in normal X ‐junctions (NXB) requires a branching angle as narrow as 0.2°. A TSXB is thus suitable for WDM systems, yet comes in a size significantly more wide angle (and hence more compact) than an NXB. © 2001 John Wiley & Sons, Inc.
